Very interesting. I liked the Morpho Towers one especially. It looked like there was a light possibly magnetic ceiling on the last one…that seemed to catch and hold some of the metal before dropping it when specific loud sounds were expressed.

(It reminds me of the Tower of Babel that some stories say crumbled to the ground after the crowd stomped in unison around it (I think for days) while clanging loud instrumentation and voice also.) and However it fell, the Morpho Towers reminded me of the stories.

I seem to recall anaritcle about being able to make the stuff, using laser copier toner and vegetable oil, though the resulting stuff is basically ink, so it’ll stain everything. But yes, ferrofluids are awesome.
